BACKGROUND OF THE INVENTION

Field of the Invention

The disclosed invention relates generally to a method and apparatus for user testing and video branching, and more particularly, but not by way of limitation, relating to a method and apparatus for dynamic advertisements driven by real-time user reaction based A/B testing and consequent video branching.

Description of the Related Art

In business there has been an increased need for testing users for a review of products in a more efficient manner Therefore, videos have been used a vehicle for testing of products. Dynamic generation of videos is characterized by a constant change in generation of videos. Video templatization and soft real time generation of videos from templates can be carried out. Thereby, it is possible to dynamically generate videos and personalize them, over embodiments of given video templates.

A/B testing or also called split testing is an important function for many organizations that specialize in any form of advertising. In marketing and business intelligence, A/B testing compares two versions (A and B) to see which is better. For example, one can show the two variants A and B to similar visitors at the same time, and compare the two variants. Additionally, user attention and reaction based content presentation is a current topic of research, such as eye tracking based content presentation (zoom in, zoom out, etc.).

However, the current methods are unable to provide an efficient means of live testing and a method of providing accurate feedback of a testing comparison in real-time. Currently, much resources and time are needed to analyze the testing. Moreover, the testing is not automatically performed. Much user intervention is currently needed.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENTS

The invention will now be described with reference to the drawing figures, in which like reference numerals refer to like parts throughout. It is emphasized that, according to common practice, the various features of the drawing are not necessary to scale. On the contrary, the dimensions of the various features can be arbitrarily expanded or reduced for clarity. Exemplary embodiments are provided below for illustration purposes and do not limit the claims.

Currently, there is no live testing, monitoring and analyzing of the audience reaction, and dynamically updating a video (as it moves forward) based upon the test results. Such a monitoring is not performed with the video including analyzing all parts of the video itself.

Video content adoption or video branching in real-time setting, testing it live across a wide audience, as well as at a personal level in soft real time, based upon the outcome of any live testing, monitoring and analysis, is also missing.

Further, the current state of the art does not attempt to do any form of live (real-time) split-testing on a video broadcasted over a given channel, to measure the comparative effectiveness of different morphs of the same video, or attempt to gauge the user's current best focus zone on the screen.

Consequently, advertising delivery optimization, including punch line delivery (e.g., “drink ABC Cola”, where “ABC Cola” is a product), is also suboptimal with respect to the known/expected reaction of the viewers (less personalized than is possible to attain).

Referring to FIGS. 1 and 2, one of the features of an example embodiment is to present a user with a video 100, the “later” part 120 (e.g., later frames of the video stream 100) of which would be dynamically initialized from a given template, using a video template initializer module, based upon the insights derived from measuring and A/B split testing of user's reaction and mood towards the earlier part of the video (210).

Moreover, an earlier part of the video 110 (e.g., early frames of the video stream) may or may not be a video template, depending upon the requirements of the later part of the video, and the length of the movie (220). For example, if a video is long enough, the A/B split testing may be done just for the current viewer across timeline within the video by having multiple segments to conduct a series of tests, and thereby “better” personalize the later part of the video using the insight derived from the tests.

On the contrary, referring to FIGS. 3 and 1, for a short video (e.g., 20 second advertisement), when there is not enough time to conduct A/B split testing on an individual user over a series of tests, a computer device can run in parallel different short tests on different segments of viewers watching from different devices, (e.g., a segment of known like-minded people or known social friends) for the earlier part of the video 110 (step 310) and then choose the later part 120 of the video embodiment en-mass to maximize the satisfaction for the maximum number of viewers (though not necessarily in a well-personalized manner for all viewers) (step 320).

Referring to FIG. 4, the video snippet (content) chosen by the dynamic template initialization 400, initializing the later part 120 of the video 100, would depend upon a few factors, as explained below.

One factor is a set of devices, such as a wearable glass, a mobile phone based camera or webcam, an eye-tracking device (such as TOBII, EYE LINK, EYE TRIBE, etc.) to observe viewer reaction 410, and a module to infer the semantics of such reaction 450.

Another factor would be a module to measure the reaction the user at a given instant of time 420, with respect to the video shown (for example, did the user focus on the screen at all or look away, if they focused on the screen then which part of the screen they focused more, did their heart beat increase a lot while watching, did they start blinking a lot or sweating, etc.).

Another factor is a module to identify the set of best embodiments 430 for the given viewer of the later part of the video, to embody the video template existing at the later part of the video, given the reaction of the viewer, based upon live (real-time) A/B split testing of the first (test) part of the video (over a series of test video segments lying within the test part of the video).

In FIG. 4, there is shown another module to perform individual A/B testing 460. This module for A/B testing 460 will perform individual A/B testing. The result of this will be made available to module identifying the best embodiment for a later part of the video.

Another factor is a module to conduct A/B split testing in parallel 440, in a live setting in real-time, across a multitude of audiences watching over multiple devices, for the first (test) part of the video, by presenting different test video segments, and aggregate per segment the observations in real-time to choose from a given set of candidates, the embodiments of the dynamic portion of the video template catered to different segments of viewers.

Inputs

A processing device 500 can include the following inputs.

There can be a video template (for example, an advertisement), with a first (“test”) portion 110 that comprises of one or more test video segment, and a later portion 120 that comprises of one or more “templates” that need to be filled in dynamically after the first portion of the video has been run but the later portion has not yet been run 510. A set of permissible embodiments of the template video, including but not limited to a conclusion, a punch line.

Another input can be a device to monitor and analyze, in soft real time, the reaction of the viewers, towards the video shown 520. Optional auxiliary parameters 530 can be the environment, geography, time of day, context, user profiles etc.

Optional wearable devices that capture some of the biological parameters of a user (such as some of heart rate, breathing rate, perspiration rate, eye blinking rate, brain EEG signals etc.), which will be used to measure user reaction in-depth.

Outputs

Outputs can includes fully formed set of videos (in which, all templates would have been initialized) 540, in which, each video has been adopted by initializing the templates, using the results of A/B split testing of user's reaction to the initial segments of the video (the one or more test segments). The output can also include the results of A/B split-testing across a segment of viewers 550.

Sample Embodiment 1 (Short Ad (Advertisement))

A video advertisement for a Cola product, “ABC Cola”, of 30 seconds of length, comprising of 3 segments, out of which, the first 15 seconds has 2 pre-determined versions, the next 5 seconds also has 2 pre-determined versions, and the third one, 10 seconds long, has 2×2=4 pre-determined versions.

Referring to FIG. 6, for the video stream 602, the advertisement will be catered to audience in Colorado 660 and California 670. For example, sensors can be located in Colorado 660 and California 670 and transmitted to the analyzing device or server 600 in a third location or in the clouds in a virtual server. The locations 660 and 670 can also include display devices for viewing the video stream 602 at the two remote locations. Therefore, the server 600 can be a virtual server in the clouds. The punchline to be delivered is “drink ABC Cola”. The following would be the set of segments and versions.

-   -   Segment 1 (15 seconds) 610:     -   Version 1_1: A scene on the hills 642; and     -   Version 1_2: A scene on the beach 644.     -   Segment 2 (5 seconds) 620:     -   Version 2_1: A scene on the hills 646; and     -   Version 2_2: A scene on the beach 648.     -   Segment 3 (10 seconds) 630:     -   Version 3_1: A scene that start on the hills and ends on the         hills and delivers the punchline 650;     -   Version 3_2: A scene that start on the hills and ends on the         beach and delivers the punchline 652;     -   Version 3_3: A scene that start on the beach and ends on the         hills and delivers the punchline 654; and     -   Version 3_4: A scene that start on the beach and ends on the         beach and delivers the punchline 656.

The audience population is randomly divided into two approximately equal halves, for each of Colorado 660 and California 670. On one half of each geographical location 660 and 670, version 1_1 (642) is delivered, and on the other half, version 1_2 (644) is delivered, and this lasts for the first 15 seconds of the advertisement.

The reaction of the audience at each of the locations 660 and 670 are captured in each of the two segments, and these are analyzed by the server 600. While the analysis happens (which takes some time), version 2_1 (“hill” version) 646 is shown to the audience that had seen version 1_1 (“hill” version) 642, and version 2_2 (“beach” version) 648 is shown to the audience that had seen version 1_2 (“beach” version) 644.

In the meantime, the analysis finds that the advertisement is engaging the California audience 670 more with the “hill” version but the Colorado 660 audience more with the “beach” version. This analysis is reflected on catering the final segment of the advertisement to the audience, as described subsequently.

In California 670, the audience segment that was shown “hill” (versions 1_1 and 2_1) are shown the punchline using version 3_1 (“hill-to-hill”). The audience segment that was shown “beach” (versions 1_2 (644) and 2_2 (648)) are shown the punch line using version 3_3 (“beach-to-hill”) 654.

In Colorado 660, audience segment that was shown “hill” (versions 1_1 (642) and 2_1 (646)) are shown the punch line using version 3_2 (“hill-to-beach”) 652. The audience segment that was shown the “beach” (versions 1_2 and 2_2) 644 and 648 are shown the punch line using version 3_4 (“beach-to-beach”) 656.

Sample Embodiment 2 (Long Ad)

Referring to FIG. 7, a second sample embodiment uses a long ad (advertisement) 702. A video ad of Cola of 300 seconds of length 702, includes 5 segments of 50 seconds of length each (702-710), a 6^(th) segment of 5 seconds (712), and a 7^(th) segment that is 45 seconds 714 that is processed on the server 600.

The first segment 702 is shown on a beach, which, at the end, transits gracefully to an agricultural landscape. The second segment 704 is shown on an agricultural landscape, which, at the end, transits gracefully to a well-flowered colorful garden. The third segment 706 is shown on a well-flowered colorful garden, which, at the end, transits gracefully to a hill top. The fourth segment 708 is shown on a hill top, which, at the end, transits gracefully to a forest. The fifth segment 710 is shown in a forest. The sixth segment 712 has also a forest (to enable the computation by the server till the previous step to complete). The seventh segment 714 has 5 versions, and contains a plurality of punch lines:

-   -   Version 1: the punchline is delivered on a beach, transiting         from a forest 716;     -   Version 2: the punchline is delivered on an agricultural         landscape, transiting from a forest 718;     -   Version 3: the punchline is delivered on a well-flowered         colorful garden, transiting from a forest 720;     -   Version 4: the punchline is delivered on a hill top, transiting         from a forest 722; and     -   Version 5: the punchline is delivered on a forest, remaining         within a forest 724.

The punch line to be delivered can be for example, “drink ABC Cola”. An individual audience member or a plurality of audience members can be watching the TV at a single location 660 or multiple locations 660 and 670. The reactions of audience are analyzed after the first 5 segments are shown at server 600. It is noticed that the audience liked the beach version 716 the best. Hence, version 1 of the punch line 716 was chosen to deliver the punch line for the long advisement 702.

Please note that an audio stream can be substituted for the video stream in the long advertisement 702 or short advertisement 602. Additionally, audio output devices can be substituted for the displays for audio output portion of the displays can be used. Moreover, other types of output devices can be used for review by the audience. In addition, a plurality of different sensors could be used to receive the feedback from the audience to the server 600 when reviewing the advertisements 702 and 602.

FIG. 8 illustrates an example system architecture diagram, according to an example embodiment. The Server 600 can include a user reaction and eye tracking analyzer that receives the input 814 from the display and sensors at the first viewing station 822. When an individual audience member 824 views the advertisement, the sensors at the first viewing station 822 sends the user attention and reaction signal 814 to the user reaction and eye tracking analyzer 802 on the server 600. A plurality of audience groups 826 can view at the second viewing station 820. The second viewing station can include, for example televisions with gaze tracking enabled to send back to the user reaction and eye tracking analyzer 802 which outputs the pertinent information of user reaction and eye tracking of the audience.

The user reaction and eye tracking analyzer then sends an output to the split video manager 804 for splitting the video. The video-motif-to video-type inferencer 806 receives the output from the user reaction and eye tracking analyzer 802 for processing from the video motif to video type. The video composer 808 receives raw video stored in the video repository 810, and also the policy and rules information stored in the policy and privacy rules storage device 812. The video composer 808 then processes the information received from the video-motif-to video-type inferencer 806, with the information from the video repository 810 and policy and privacy rules storage unit 812 in order to compose the video for viewing by the audience 824 and 826 at the two different locations. The video composer 802 then stitches the video segments to form a full video to send back via an output signal 816 to the viewing stations 822 and 820.

Therefore, as shown in the above, the technology that enables instantiating video templates, from a set of possible embodiments is shown. Moreover, devices that allow monitoring and analyzing viewer focus, and can be easily adopted to identify an approximate zone of a given screen that a given viewer is focusing towards.

Additionally, other devices (wearable/smart/other) that can capture some of the biological parameters of a user (such as some of heart rate, breathing rate, perspiration rate, eye blinking rate, brain EEG signals etc.) can also be used. Such devices can be provided for the individual audience users 824 and 826 that can be communicate with the viewing stations 822 and 820.

One of the features of the disclosed invention is to be able run live A/B split testing within videos, including but not limiting to advertisements, and thereby determine what resonates and deliver significant messages (such as a “punch line” in ads, e.g., “drink ABC Cola”) in a manner that would be individually or collectively the most acceptable to the viewers, as per the cognitive state they are inferred to be in. This involves presenting the viewer a video with multiple “initial”, “intermediate” and “later” parts, the “later” part of which is dynamically selected from few potential choices of the “later” parts, based on viewers' individual and collective (“group-of-viewers”) reaction to the “initial” part of the video.

Therefore, a system and methods implement a setting, in which, one of the following is implemented:

Option 1:

-   -   Different “initial” parts are shown to different audience         segments, and while the “intermediate” part of the video is         being shown, the “later” part of the video is chosen for the         entire set of audiences, based upon the recorded collective         viewer reaction, and a “later” part is chosen accordingly; and

Option 2:

-   -   For each viewer, a series of different motifs are shown during         different times within the “initial” period, and then, while the         “intermediate” part of the video is being shown, the “later”         part of the video is chosen in a personalized manner based upon         the recorded reaction of each target viewer, and a “later” part         is chosen accordingly.

These choices are implemented using a combination of the following factors:

(a) The observed viewer reaction, and the inferred semantics of such reaction, in the “initial” part of the video;

(b) Live (real-time) AB split testing of the viewer's attention on the screen;

(c) Identifying set of best choices of the “later” part of the video, given the reaction of a given viewer over multiple known segments of the given video, based upon live (real-time) AB split testing of the “initial” part of the video, for each given viewer;

(d) A/B split testing conducted in parallel, in a live setting in real time, across a multitude of audiences watching over multiple devices, for the “initial” part of the video, and observations aggregated in real-time to infer, and thereby choose embodiments of the “later” portion of the video catered to different segments of the viewers.

Example applications can be aligned to the advertising and video related products, UNICA-like products (Omni-channel marketing) can benefit from this, by implementing the disclosed invention as an improved dynamic advertising system. The disclosed invention can also be implemented in sales, marketing, and/or education videos it delivers to clients.
